About Converting Carats per Quart to Pounds per Imperial gallon
Carat per Quart and Pound per Imperial gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
pounds per imperial gallon = carats per quart × 0.00211811309878
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct carat per quart-to-pound per imperial gallon factor of 0.00211811309878.
Simple example
1 ct/qt × 0.002118113099 = 0.0021181131 lb/imp gal
1 carat per quart = 0.0021181131 pounds per imperial gallon.
Real-world example
1,000 ct/qt × 0.002118113099 = 2.118113099 lb/imp gal
1,000 carats per quart = 2.118113099 pounds per imperial gallon.
